Fitness membership stamp is usually issued to customers by fitness clubs or fitness studios as identification and vouchers. Belonging to a kind of behavior and business behavior of merchants, its main function is to make customers feel honor, encouragement, self-confidence and a sense of accomplishment.

However, if there is fraud in the issuance of the fitness membership seal, according to the General Principles of the Civil Law of People's Republic of China (PRC) and other relevant laws and regulations, customers can safeguard their legitimate rights and interests through legal channels and ask the merchants to compensate for the losses. For example, if a customer buys a badge of a fitness member, but the merchant fails to provide qualified service, resulting in the customer not being able to enjoy the fitness service normally, the customer can ask the merchant to refund the fee and bear the corresponding liability for breach of contract.
